چکیده
BACKGROUND This study compared root canal sealing ability, filled by Continuous Wave compaction and two carrier-based obturation systems, using the nuclear medicine approach. MATERIAL AND METHODS Fifty-five single-rooted extracted teeth were selected. The crowns were sectioned and each tooth was instrumented using rotary Protaper® Universal system. The roots were divided into 3 experimental groups and two control groups. Forty-five root canals were filled, using Continuous Wave, GuttaCore or Thermafil system and TopSeal sealer. Ten teeth were used as control. On the 7th days the apices were submersed in a solution of sodium pertechnetate 99mTc for 3 hours and the radioactivity was counted. RESULTS Although apical leakage in the Continuous Wave group was lower compared with GuttaCore and Thermafil groups, there was no statistical difference (p>0.05). CONCLUSIONS System B, GuttaCore and Thermafil techniques showed a similar sealing effect. Key words:Continuous wave compaction, Gutta percha core-carrier, leakage, nuclear medicine.

An In-Vitro Evaluation and Comparison of Apical Sealing Ability of Three Different Obturation Technique - Lateral Condensation, Obtura II, and Thermafil.
INTRODUCTION Success of non-surgical root canal treatment is predicted by meticulous cleaning and shaping of the root canal system, three-dimensional obturation and a well-fitting "leakage-free" coronal restoration. The techniques of obturation that are available have their own relative position in the historical development of filling techniques. Over the years, pitfalls with one technique hav...

OBJECTIVE Widespread use of rotary nickel-titanium systems has caused manufacturers to produce gutta-percha cones that match the taper of the canals prepared with these systems. Obturations with these cones may provide 3-dimensional obturation of the root canal in less time. The aim of this study was to use a fluid filtration method to compare the apical sealing ability of matched-taper single-...
